PICTURE SHOWN MAY VARY FROM ACTUAL PRODUCT

AEMs patented Air Bypass Valve virtually eliminates the chance of hydro-lock in the event you submerge the air filter of your AEM Cold Air Intake in water. On most cold air intake systems, the valve installs along the upper portion of the inlet pipe and shuts down induction at the filter when it becomes submerged, rerouting air through its external diaphragm to keep water out and air flowing in.
